减数分裂教学中重组值的教学,是高等医药院校遗传学中教学的关键点和难点.作者利用泊松分布的作图函数和蝗虫的精子形成过程装片制作、观察实验教学相结合的方法,不仅使学生掌握了减数分裂的基本知识,同时也使学生掌握了减数分裂最大重组值不超过50%的教学难点.%Teaching of the biggest value of recombination frequency between two linked genes is the key point. Used teaching strategy by mapping function and experiment in medical school, the reason why the biggest value of recombination frequency between two linked genes is no more than 50% and the related knowledge of meiosis are well explained.
